Hi,
Got my new s3 two weeks ago and so far happy with the picture quality.But some times I get overexposed photos like this one.Also there are times I accidently hit the Iso button and change it a higher iso.what should
be done to fix the over exposure?Is this the typically called flare!
Exposure Bias Value = ±0EV
Aperture Value = 3.63 AV
Shutter Speed Value = 6.31 TV
This picture is one direct from the camera.No pp

In the case of the above picture you would need a graduated neutral density (GND) filter to prevent the sky from being blown out or a polarizer filter.
This link http://www.tiffen.com/camera_filters.htm will tell you what each filter will do.

Wish there were a way to see this photo with the different filters applied. I am never sure when to use my PL or ND4. I do not have a graduated ND although I know those are better.

The effect you see here is not over-exposure or flare, but blown highlights. The majority of your picture is perfectly exposed, its just the sky that is over-exposed.
The problem is not limited to the S3, but to cameras in general.
What I would suggest (assuming that you are shooting on a tripod), is take 2 pictures. One just like the one you took, plus a second one that would better expose the sky (you can use exposure compensation at -1 or so to accomplish this). Then at home in Photoshop, I would combine the two pictures, using the sky from one and the rest from the other.

Circular Polarizer with -1/3 EV should fix that :cool:
Also turning down the contrast in the custom colors in Program mode can help.

Just a thought.How will a Dslr with a kit lens respond in these circumstances?

I can't speak from experience, but my guess would be it would respond the same way. You would need a filter to bring the blue out in the sky no matter what lens you had. Again...this is an assumption on my part.

Let me suggest "Understanding Exposure" by Bryan Peterson There is only so much you can do to compensate for the harse light of the Sun. The best time to shoot during the day is an hour or so after sunrise and before sunset. Light effects every aspect of a photo you have to make it your business to understand "how" to achieve the results you want. My personal favorite is a semi overcast day where the Sun pops in and out all the time. As a rule on a clear sunlit day at midday expect bad results. hth

Thanks Xailo for confirming that.A nikkon d40 was also offered at the time of purchase of the s3,both were used ones.I cld have frustrated if the Nikkon
D40 did the same job in these circumstances.Ended up ordering the following for my S3.Happy s3 owner now:) Circular Polarizer seems to be a bit expensive and looked upon a uv filter this time.
